What is OCPP?
OCPP stands for Open Charge Point Protocol. It is an open-source, free-of-cost communication protocol created by the Open Charge Alliance (OCA) that enables EV charging stations and central management systems to connect and communicate. In other words, it allows various EV charger brands and software platforms to speak with one another, just as USB enables multiple devices to communicate with your computer.
Why Should Businesses Care About OCPP?
If you’re a company looking at EV charging or already have chargers installed, compliance with OCPP liberates you from being tied to a single manufacturer or software firm. This enables you to:
- Combine and match several hardware and software providers
- Scale your charging infrastructure more easily
- Avoid costly commercial systems
Key Benefits of OCPP
Interoperability: OCPP enables communication between EV chargers (charge points) and a central management system regardless of the brand.
Smart Charging: OCPP facilitates smart charging features like load balancing, demand response, and user prioritisation to be integrated.
Remote Management: Remotely monitor, maintain, and diagnose EV charging stations via a central management console.
Future-Proofing: As it is open standards-based, you are less vulnerable to systems becoming outdated.
OCPP Versions Explained
The Open Charge Point Protocol (OCPP) has been developed over the years, and each subsequent release has added more features to address the increasing needs of EV charging infrastructure. OCPP 1.6 is a popular version appreciated for its stability and broad industry support. It provides essential features such as smart charging, which helps companies save energy and operational expenditures, and management and control through remote operation, making it convenient to manage chargers via a central management system. Since it is stable and operationally proven, most charging station management systems are based on this version, and it is a suitable option for EV charging companies with minimal experience.
For most organisations, OCPP 1.6 is adequate to facilitate secure EV charger installation and core smart charging features. It delivers the essential tools to run and manage a charging network efficiently. Yet, with increasing EV uptake and more complicated energy requirements, some companies are looking for more extensive functionality. This is where OCPP 2.0.1 comes in with a new standard and future-proof scalability.
OCPP 2.0.1 brings many improvements, such as enhanced security, more detailed diagnostics, and better energy management system support. One of its most significant improvements is the addition of ISO 15118 support, which provides Plug & Charge functionality. This allows EV drivers to plug their car into a charger and charge immediately, no apps or RFID cards needed. OCPP 2.0.1 also enables more accurate data exchange and integration with building systems, allowing companies greater control over how EV charging is coordinated with overall energy use.
So, although OCPP 1.6 is a good minimum for most companies, choosing hardware that’s OCPP 2.0.1-ready, future-proofs you for the years to come. opting for OCPP 2.0.1-ready hardware ensures long-term flexibility.
How OCPP Supports Your Charging Infrastructure
OCPP allows for simpler centralised management of EV charging stations through management software. This allows businesses to monitor usage, apply access controls, and monitor charger health. It also allows your charging station management system to be integrated with other solutions, such as energy monitoring equipment and building management systems.
The Open Charge Alliance is the global association behind OCPP. It advocates for open standards in electric vehicle charging and collaborates with stakeholders throughout the EV ecosystem to assist compliance, drive development, and encourage broad adoption.
As the market for electric vehicles expands, businesses require charging infrastructure that is scalable, flexible, and simple to operate. By selecting OCPP-compliant solutions, you can guarantee that your central management systems and EV chargers work in alignment with one another, regardless of the vendors you choose. If you’re overseeing several EV charging stations or directing a large-scale deployment, OCPP provides the flexibility and functionality to turn your strategy into action.
